The PAM3103 is a positive, adjustable linear regulator. It features low quiescent current (65μA typ.) and low dropout voltage, making it ideal for battery powered applications. The output voltage is adjustable from 1.2V through 5V. Its high PSRR makes it useful in applications that require AC noise suppression on the input power supply. Spacesaving TSOT25 and SOT353(SC70-5) packages are attractive for portable and handheld applications. It has both thermal shutdown and a current limit features to prevent device failure under extreme operating conditions. It is stable with an output capacitor of 2.2μF or greater.


  • Low Dropout Voltage: 180mV@ 300mA ( VO = 3.3V)
